Suggest to use wp_enqueue_style instead of echo for CSS styles

I’ve been using sharebar for long time so far. I’d like to know if you can consider to use the WordPress enqueue features in order to enqueue the required CSS styles, or a filter. So far, I noticed the CSS is inserted using an echo (see here: http://take.ms/s2niu ).

It will be great if you can use wp_enqueue_style instead. Why I am asking about this? Because in my case I am trying to do some optimizations and minification of the css/js files and your styles are being added with media=”screen”.
